1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

1. Read and understand the entire owner's manual before attempting assembly or operation .

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace warning labels if they become obscured or removed.

4. This bench grinder is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a bench grinder, do not use until proper training and knowledge have been obtained.

5. Do not use this bench grinder for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always use safety glasses. Use the grinder’s eye shields and spark guards. (Everyday ey eglasses

only have impact resistant lenses; they are NOT safety glasses.) Also use face or dust mask if

cutting operation is dusty.

7. Wear proper apparel. Do not wear loose clothing, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.

8. Wear protective clothing such as apron or safety shoes, where the grinding activity presents a hazard to the operator.

9. Wear ear protectors (plugs or muffs) if the particular work requires it.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after completion of maintenance.

16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

17. Provide for adequate space surrounding work area and non-glare, overhead lighting.

18. Keep the floor around the machine clean and free of scrap material, oil and grease.

19. Keep visitors a safe distance from the work area. Keep children away.

20. Make your workshop child proof with padlocks, master switches or by removing starter keys.

21. Give your work undivided attention. Looking around, carrying on a conversation and “horseplay” are careless acts that can result in serious injury.

22. Keep proper footing and balance at all times so that you do not fall into or lean against the grinding wheel or other moving parts. Do not overreach or use excessive force to perform any machine operation.

23. Disconnect grinder before servicing and when changing abrasive wheels.

24. Use recommended accessories. The use of improper accessories may cause risk of injury to persons.

25. Turn off the machine before cleaning. Use a brush to remove chips or debris — do not use your hands.

26. Never leave the grinder running unattended. Turn power off and do not leave machine until wheels come to a complete stop.

27. Remove loose items and unnecessary work pieces from the area before starting the grinder.

28. Don’t use in dangerous environment. Don’t use power tools in damp or wet location, or expose them to rain. Don’t use this grinder in a flammable environment. Keep work area well lighted.

29. Keep work area clean. Cluttered areas and benches invite accidents.

30. Use right tool. Don't force tool or attachment to do a job for which it was not designed.

31. Use proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 (see sect. 7.2) shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

32. Secure work. Use clamps or a vise to hold work when practical. It's safer than using your hand and it frees both hands to operate tool.

33. Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

34. Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

35. Direction of feed. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.

36. Do not overtighten wheel nut.

37. Frequently clean grinding dust from beneath grinder.

38. Use grinding wheel suitable for speed of grinder.

39. Inspect abrasive wheels for cracks or other forms of damage. Perform a “ring test” to check wheel integrity. Do not use a faulty or damaged wheel.

40. Verify that maximum RPM of abrasive wheels is compatible with speed of grinder. Do not remove the blotter (label) from either side of a grinding wheel.

41. Allow abrasive wheels to reach full RPM before starting the grinding operation.

42. Do not crowd the work so that the wheels slow.

43. Tool rests should be adjusted to approximately 1/16” from wheel surface.

44. Do not grind on the side of a wheel; do all work on the grinding face or edge near the tool rest.

45. Do not grind aluminum or magnesium, as these may pose a fire hazard.

46. Use only the flanges that are furnished with the grinder.

6.0 Electrical connections

Electrical connections should be made by a qualified electrician in compliance with all relevant codes. This tool must be properly grounded.

The model IBG-8 (#578008) and IBG-10 (#578010) bench grinders are prewired for 115V power, and are supplied with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in A, Figure 8. These grinders may be converted to 230V power, see sect. 6.3.

The model IBG-12 (#578012) is rated for 230V only, and is not supplied with a plug.

Before connecting to power source, be sure switch is in off position.

It is recommended that the grinders (all models) be connected to a 15 amp circuit with a 15 amp circuit breaker or time-delay fuse marked “D”. Local

codes take precedence over recommendations.

Check with a qualified

electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in A, Figure

8. An adapter, shown in B and C, may be used to connect this plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. This adapter is not permitted in Canada. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

3. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150 - 250 volts, inclusive:

Figure 8: plug configurations

6.1 Grounding instructions

1. All Grounded, Cord-connected Tools:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in D, Figure

8. A grounding plug may be installed, that looks like the plug illustrated in D; or the grinder may be “hard-wired” to a panel, provided there is a disconnect for the operator.

Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

6.2 Extension cords

The use of extension cords is discouraged. Try to position equipment near the power source. If an extension cord becomes necessary, use only three-wire extension cords that have three-prong grounding type plugs and three-prong receptacles that accept the tool's plug. Replace or repair damaged or worn cord immediately.

Make sure your extension cord is good condition, and is heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number (AWG), the heavier the cord.

6.3 Voltage conversion

To change voltage input to 230V on the IBG-8 and IBG-10:

1. Turn grinder over and remove the base plate.

2. Rewire the leads according to the appropriate

diagram in sect. 13.0.

3. Remove the existing plug from the grinder

cable and attach a UL/CSA listed plug designed for 230V power.

7.0 Operation

A bench grinder is designed for hand-grinding operations such as sharpening chisels, screwdrivers, drill bits, removing excess metal, and smoothing metal surfaces.

A Medium Grain Abrasive Grinding Wheel is suitable for rough grinding where a considerable amount of metal must be removed or when obtaining a smooth finish is not important.

A Fine Grain Abrasive Grinding Wheel should be used for sharpening tools or grinding to close size tolerances because it removes metal more gradually for precision grinding and achieves a smoother finish.

Always use approved safety glasses or face shield while operating grinder. Failure to comply may cause serious injury.

7.1 On/Off Switch

IBG-8, IBG-10: Pull the paddle switch (A, Figure 9)

to start grinder, push to stop. The safety key (A can be removed to prevent unauthorized use of the grinder. The safety key must be inserted to restart the grinder.

IBG-12: Push green button to start grinder. Push red button to stop.

)

7.2 Precautions

1. Before starting the grinder, turn the wheels by hand to verify that they are clear of obstructions and they turn freely. The tool rests and spark guards should not touch the wheel.

2. Keep tool rests and spark guards to within 1/16" of the grinding wheel.

3. Turn on the grinder and allow it to reach full running speed before starting to grind.

4. Adjust the eye shields as needed.

5. Keep a steady, moderate pressure on the workpiece and keep it moving at an even pace for smooth grinding. Pressing too hard overheats the motor and prematurely wears the grinding wheels. Note the original bevel angle on the item to be sharpened and try to maintain the same shape. The grinding wheel should rotate into the object being sharpened.

6. If grinding a narrow workpiece, slide it laterally across the width of the wheel. Using the full width of the wheel will help prevent a groove from forming at one place on the wheel.

7. Keep the water pot filled with water and dip your work into it regularly to prevent overheating. Overheating can weaken metals. Do not apply water directly to the grinding wheels.

8. Do not use the side of the grinding wheel; this puts dangerous stress on the wheel.

9. When the wheel becomes loaded or dull, use an approved grinding wheel dresser and dress the wheel face.
